Dear all,
I have a general question about using step up/down into a charger IC.
specifically, I'm using a step up TPS43061 and charger IC BQ24600.
what needs to be taken in considuration when steping up/down voltage into a switching charger IC?
for example: is there an advantage to choos a frequency for the DC/DC same or harmony of the charger IC frequency? (Fsw) is there any effect?
is there a situation when both charger IC and step up/down are synced backwards? meaning the charger IC samples the input exactly when the duty cycle is off?
how about recommended Vin Vout difference voltages for the charger IC?
thanks for any assistance,
